In order to study the factors affecting the seismic performance of the prefabricated steel composite wall,its pseudo-static test was taken as the research object,and the ABAQUS and OpenSees software were used to simulate the wall numerically.In ABAQUS,a solid unit was used to build a model,and the horizontal monotone loading was carried out.The results show that the actual failure position of each specimen is the same as that of the stress nephogram,and the calculated load-displacement curve is in good agreement with the test result.In OpenSees,the wall was simplified into a rigid frame-diagonal bar model,and the fiber element was used to build the model,and the low cycle reciprocating loading was carried out.The rationality of the model was verified by comparing with the measured hysteresis curve.Based on specimen SCW-1,the key parameters were further analyzed.The results show that the lateral stiffness and bearing capacity of the wall increase with the increase of axial compression ratio and steel content of the frame column,but the displacement ductility and energy dissipation capacity decrease slightly.On the contrary,with the increase of shear span ratio,the lateral stiffness and bearing capacity of the wall decrease,and the displacement ductility and energy dissipation capacity increase gradually.
